FASTENING FOR SECTIONAL TUBING.

Application filed August 2, 1920.

To all whom it may concern:

Be it known that I, Josnrrr E. BUCKLAND, a citizen of the United States of America, and resident of Elkhart, in the county of 5 Morton and State of Kansas, have invented certain new and useful Improvements in F astenings for Sectional Tubing, of which the following is a specification.

This invention relates to casings or tubings and more particularly to means forsecuring sections of tubings at their joints whereby the sections may be detachably connected and whereby the securing means will be held against accidental dissociation or disengagement during the handling or manipulation of the tubing.

A still further object of this invention is to produce a sectional tubing and securing means associated therewith, the said securing means having interlocking or interengaging ends, which ends prior to their being interlocked, may be manipulated for causing the said interlocking engagement by those who are without extraordinary skill in the manipulation of sheet metal.

A still further object of this invention is to produce a securing device of the character indicated having advantages in points of efliciency and durability while the same is comparatively inexpensive.

WVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote correspond ing parts in the several views, and in which Figure 1 illustrates a View in elevation of a fragment of the tubing showing the sections thereof connected;

4 Figure 2 illustrates a longitudinal sectional view thereof; and

Figure 3 lllustrates a sectional View on the line 33 of Figure 1.

In these drawings 5 and 6 denote sections of tubing, the former of which in the present embodiment of the invention, is shown as extending into the latter.

The section 5 has a band 7 secured on it by fastenings 8 such as rivets, and the sec- Serial .No. 400,761.

tion 6 has a band 9 secured on it by fastenings 10 such as rivets. The rivets are spaced apart from each other, and between the rivets the bands are free of the tubing, and

in the spaces between the bands and tubing, the tie straps 11 are inserted, the said straps each comprising a metallic strip of pliable material but comparatively rigid so that when the parts of the ties are interlocked, as will presently appear, the metal will not readily yield or bend to permit a disengagement of the interlocking parts of the ties.

As a disclosure of one of the ties will be applicable to all of them, since they are of like construction, they will be described in the singular.

Each tie or metallic strip is of such length as to embrace and extend across the space between the said bands, and in the construction of the ties, one end 12 has an inwardly bent hook 13 whereas the other end is straight. After the tie has been applied to the band as shown in Figure 1, the hooked end is bent outwardly across the band and the other end is bent outwardly, and the tongue 14 thereof is then shaped to form a hook to lie across and interlock with the hook 13 so that the ends of the tie interlock in a manner to prevent their disengagement and the tubing may be moved with relation to the well or hole into which it is to be placed without liability of an accidental disengagement of the ties or the disconnection of the ends of the tube sections.

From an inspection of the drawing, it will be seen that the band 7 having the tie interposed between its edge and the edge of the end of the larger section of tubing, acts as an abutment to aid in sustaining the telescopic sections in proper relation to each other and to a great extent relieves the strain on the joint between the ends of the ties.

I claim:

In a connection for telescoping sections of well tubing in which the smaller section is above the larger section into which it fits, a band on the outer surface of each section near the joint between the sections, securing devices comprising flexible ties inserted between the bands and the said sections, each of said ties being bent downwardly over the band of the smaller section and upwardly over the band of the larger section, the

together, the joint betwen the hooked portions being guarded by the upwardly extending portion of the tie whereby the shoulder 10 formed by the interlocking of the said portions is at the top of the joint between the said sections of tubing. 7
